Number of mass shootings in US

Unfortunately, there are more and more mass shootings in the United States of America. Keep in mind the fact that there have been 16 mass shootings in the US in 2013. These mass shootings are real tragedies. Statistics show the fact that guns have killed about 24,580 Americans since Newtown. This is definitely something. Unfortunately, the main idea is that mass shootings have become too common. Not too many people know that the FBI’s definition of mass murder is the slaying of four or more people.
